I have a 17" Gateway laptop from 2007 with Vista installed. When I start up the laptop the icons appear small and the desktop background is the normal size how I like it. Then I'll close the laptop and when I open it back up the icons get bigger and the screen looks like it's on zoom for blind people mode. Then it alternates after each time I open and close the laptop. I've looked through the settings I'm familiar with but can't fix it. It's just annoying but everything else functions fine. Any suggestions?
